“For most mammals,” writes Science Magazine’s Elizabeth Pennisi, “size matters: Large ones, such as elephants and whales, live far longer than small ones like rodents. But among dogs, that rule is reversed. Tiny Chihuahuas, for example, can live up to 15 years—8 years longer than their much larger cousins, Great Danes. Now, a team of undergraduates may be closer to figuring out why. The most likely culprit? More harmful oxygen free radicals in fast-growing, fuel-burning puppies.”
